There's no need to remind Shavlik Randolph that his second, 10-day contract with the Boston Celtics is expiring soon.

When the Celtics signed him, it was to use him primarily for those times when the C's might be short a body.

Saturday was one of those times and Randolph indeed rose to the occasion in Boston's 105-88 win.

Randolph had six points and a team-high eight rebounds in just over 15 minutes of court time.

"He (Randolph) was great," said Celtics coach Doc Rivers. "He just came in and made things happen; rebounded the heck out of the ball, both ends, offense and defense; I was really happy with him."

It was the kind of performance that will bode well for his chances of being kept around for the remainder of the season.

Even with the strong showing, Randolph knows opportunities to play as much as he did on Saturday will be few and far between, even if the C's decided to keep him around for the remainder of the season.

Randolph's role in Boston is much different than the one he had in the Chinese Basketball Association this past season when he averaged 32 points and 14.6 rebounds per game and with 1.4 assists and 1.7 steals while playing 36.5 minutes per game.

The level of competition isn't the only significant difference for Randolph who has played for three other NBA teams (Philadelphia, Portland and Miami).

"The biggest adjustment is my role on the team," Randolph said. "In China I was obviously the man, I had plays called for me whenever I wanted, I could shoot when I wanted. Coming into a situation where most games (with the Celtics) I'm not going to play unless someone gets hurt or somebody's in foul trouble, and when I do play I have to play off other people ... I have to completely 180 (degree) my role but it's a role that I'm used to and very comfortable with."

Most of what Randolph accomplished on Saturday had to do with effort, which is exactly what the C's will be looking for whenever they reach into the deep end of the bench and pluck him or the C's other 10-day contract guy, D.J. White.

Although White didn't play as much, it's hard to ignore his six points in just five minutes of action Saturday night.

Both have shown the ability to make the most of their opportunities to play, which have been and will most likely continue to be limited as long as they are in Boston.

Aware of this, you won't hear any complaints from either player on their roles.

"Just trying to learn as much as I can, and stay ready when my number's called," said White.

Added Randolph: "There's a lot of great players on this team. My role is to play off of them. It's not that hard; just rebound everything I can get my hands on. And if I'm given an open shot, try to hit it and if I get it around the basket, try and finish opportunistically. That's what I'm going to try and do."
